MACHINE FOR FORGING CAR-AXLES AND OTHER METAL ARTICLES.

SPECIFICATION forming part of Letters Patent No. 319,752, dated June 9, 1885.

Application filed March 26, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE F. SIMoNDs, of Fitchburg, in the county of Worcester and State of Massachusetts, have invented certain Improvements in Machines for Forging Oar- Axles, Gun-Blanks, and other Metal Articles;

and I hereby declare the following to be a full,

clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a perspective view of my improved machine. Fig. 2 is a perspective View of the machine, the parts out in longitudinal vertical section. Fig. 3 is avertical cross-section of the same with the platens in the position shown in Fig. 2.

My invention consists in certain combinations and arrangements of mechanical devices, car-axles, gun-blanks, and other metal articles, as hereinafter fully described, and specifically pointed out in the claims.

In order that those skilled in the art may make and use my invention, I will proceed to describe the manner in which I have carried it out. a

In the said drawings, A is a bed or support, mounted in any desirable way, and hav ing extending along each edge projecting ribs a a, into the inner faces of which are out ways or grooves a a, to receive and sustain the edges of the platen B. This platen B has on its lower face, in a central longitudinal line, a rack-bar, b, which engages with a pinion, I), located on shaft d,under the center of the bed of the machine, and driven by shaft (1 and gearing d, d, and d, actuated by pulley 0, moved by belt 0 from an ordinary reversing-pulley on the counter-shafting. (Not shown in the drawings.) Mounted on shaft d, on each side of the pinion b, are rollers 10 11, which back up and strengthen platen B against the thrust of the billet or blank being worked upon.

The frame A carries a vertical yoke, D, having four supports or standards, D, and a central screw, D, and hand-wheel D. Se-

cured to standards D by means of ears or overlapping plates e e, which engage grooves or recesses 12 12 in the standards, so as to have a vertical movement therein, is a platen-sustaining carriage, E, having on its outer edges downwardly-projecting ribs or flanges f, provided on their inner faces with grooves f, for the reception of ribs f on the edges of an upper platen, F.

On a centrallongitudinal line the upper surface of the platen F is provided with a rackbar, a, similar to rack-bar b on thelower side of platen B, and said rack'bar e engages with and is driven by a pinion, e, shaft 6, and gear-wheel f, through. themedium of pinion 6, moiinted in the link-hanger i, and gears d" d, with their pulley G.

On each side of pinion e", and on the same shaft 6', are rollers 13 14,which back up and sustain platen F against the thrust of the work and prevent the platen from springing.

On the center of the platensustaining carriage E is a pillow-block, is, secured by bolts k k, and forming a bearing atl for the lower end of the screw D", the thread of said screw fitting a tap, Z, in the center of the top of yoke D, and a collar, m, fixed to the screw, bears on the top of the pillow-block. (See Fig. 2.) A washer and jam-nuts on the lower end of the screw prevent it from being with- .drawn from the pillow-block when the screw is run up to raise carriage E and platen F, with the driving devices and rolls, and when the carriage E is to be forced down to crowd the platen F toward platen B, so as to bring their working-faces more nearly together, the collar m sustains the thrust of the screw.-

When an article is to be subjected to the action of the platens, the upper platen is raised by drawing up carriage E through the medium of screw D. The article is inserted between the platens, the upper platen is brought down by the screw on the article, and, by means of the gearing described, the platens are reciprocated alternately in opposite directions, and press or shape or otherwise affect the article to the point desired, the platens being meanwhile backed or braced by rolls l0 l1 13 14 on the same shafts which actuate the platens.

The number of pillow-blocks and screws to sustain themovable carriage may be increased or diminished, accordingly as it may be desir able or the exigencies of the work may demand.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent; is

1. A fixed bearing bed or frame provided with grooves to support a movable platen and a vertically adjustable moving frame pro.-

vided with grooves to sustain a movable platen, in-combination with platens B F, con-- structed substantially as and for the purpose set forth.

2. The yoke D, provided with grooves or recesses 12 12, in combination with the vertically-adjustable carriage E, provided with overlapping plates 0 e and platen F, substantially as and for the purpose described.

3. In a metal-rolling machine, two oppositely-reciprocating platens, B F, provided with central longitudinal rack-bars, in combination with a stationary supporting-frame, a
